COPPER CYLINDER BASE GASKETS

These gaskets will slightly lower the compression ratio. They are die cut from

copper sheets .020” thick (.005” thicker than stock). They are the same

thickness that GM used on air-conditioned engines.

Each .010” thickness increase ADDS 1.5 cc’s to the head chamber volume.

This equates to an approximate .225:1 compression ratio decrease in a late

engine when used in conjunction with our stackable copper head gaskets.

We DO NOT recommend the stacking of base gaskets: however, with one

copper cylinder base gasket and the proper choice of our head gaskets you

can reduce compression to the desired ratio.

Note: Actual thickness may vary + or – .002” from listed thickness.

GRAPHITE EXHAUST PACKINGS

ALL CLARK EXHAUST PACKINGS – individually or in KITS, ARE GRAPHITE!

These packings are produced to CLARK specifications and are the BEST packings that have ever been available.

GRAPHITE PACKINGS are BETTER because:

● NO bad odor the first 4-5 times you start your engine.

● STRONGER! Steel reinforced graphite is much less apt to crumble or break apart.

● GRAPHITE is much less affected by heat, moisture, oil

● GRAPHITE packings can be made to more exact dimensions and compress for a tight, leak-proof fit.

● SAFER – less apt to leak.

● NO ASBESTOS or other “MYSTERY” material.

“PLASTIC” CARB. SPACERS – These were discontinued by GM. We had the material analyzed by a lab with the instructions to give

us a BETTER “modern” material without the asbestos. The new material can take MORE heat than the originals and still has good

hot and cold flexibility and strength. We now have dies that produce parts so flat that the spacers do not have to be resurfaced (like

the originals had to be). It is still suggested you use a thin gasket above and below the “plastic” spacer. CLARK EXCLUSIVE – SEE PAGE 56

Clark’s CRANK SEALS – the BEST QUALITY

POLYACRYLATE & VITON See page 3 for correct seal installation.

Unlike some seals on the market that are made from nitrile, our regular seals are polyacrylate (as specified by major USA seal manu-

facturers). It is more expensive, has a higher temperature rating and better oil resistance. Now we also have bell housing and crank

pulley seals that are exactly the same as the original seals but produced with brown Dupont VITON. You can order any of our GASKET

OR SEAL KITS with VITON crank seals by just ADDING V to the end of the part number.

A solid copper head gasket is far superior to the stock folded steel type

gasket. The thin metal edge of stock gaskets can result in hot spots that

cause detonation and burn through. The not uniform thickness of steel

gaskets will deform the gasket surface of your aluminum heads. With solid

copper you have a uniform pressure between the cylinder and head that

provides a reliable seal without hot spots. Our copper gaskets are good for

stock through +.060 overbore.

Due to lower octane levels in the fuel available today, some pinging in the

hi-performance and turbo-charged engines is being experienced. In order to

simplify a minor reduction in compression, we offer gaskets .010” thicker

than stock (.042”) and .020” thicker (.052”).

These head gaskets are also ideal to compensate for cylinder head

resurfacing when no compression increase is desired. In many cases, .030”

or more is required for a good cleanup. Due to the solid copper design you

can “stack” these gaskets two high and mix or match the two thicknesses to

acquire the head volume desired. This practice is also helpful when putting a

turbo on hi-performance heads. Many people overlook the fact that increased

bore sizes also increase compression. These copper gaskets are made from

the correct grade of copper.

Note: Actual thickness may vary + or – .002” from listed thickness.
